UPPER- HOSE CCIIHECTIOJJ FOR RADIATOES.

Original application filed October 11, 1920, Serial No. 416,083. Divided and this application filed May 8,

T 0 all whom it may concern Be it known that I, lilnmrninn iViTTE, a citizen of the United States, residing at Minneapolis. in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Upper Hose Connections for Radiators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention provides an improved upper hose connection for automobile radiators and, generally stated, consists of the novel construction and combinations of parts hereinafter described and defined in the claims.

The present invention is filed as division of my pending application, Serial Number 416,083, filed October 11, 1920, and entitled Radiators.

In accordance with the present invention. the upper hose connection, which is in substantially the form of an elbow and is rigidly secured to the upper tank of the radiator, is provided with an integral or rigidly connected tie-rod-bracket, to which the radiator tie-rod is directly anchored. The elbow is attached to and extends over a very considerable portion of said upper tank and is utilized as an extended anchor for connecting the tie-rodbracket to the tank. This removes all danger of puncturing or distorting the upper tank under strains applied between the tie-rod and tank.

In the accompanying drawings, which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fi 1 is a rear elevation with some parts broken away, showing the upper portion of the radiator, to the upper tank of which my invention is applied;

Fig, 2 is a vertical section on the line 2-2 of Fig. 1; and

Fig. 3 is a plan view of the radiator.

The upper tank of the radiator is indicated by the numeral 8. This upper tank will be connected to the lower tank, not shown, by the usual frame and will be in communication with said lower tank through suitable tubes, which, as shown. are of the arrangement disclosed and claimed in my co-pending application above identified, the said tubes being triangular and being indicated by the numeral 10. The upper hose connection is in the form oi a tubular elbow 16 and the radiator tie-rod anchoring bracket 17 is cast integral therewith. and the said combined elbow and bracket is provided with a common angular flange 18 that its against substantially the entire rear central plate of the tank 8 and extends partly under the bot tom of said tank and is secured rigidly to said upper tank, the rear, sides and bottom. preferably by rivets and also by solder applied by what is known as the sweating operation. In Fig. 1, the rivets are indicated by the numeral. 1.9 and holes, through which solder may be sweated, are indicated by the numeral 20. By reference to Fig. 2. it will be noted that the tierod-bracket 17 is provided with a threaded hole into which is screwed the front end of the radiator tie rod 17% The tank 8 is shown as provided with the customary filling neck 21 having a remov able cap 22.

The efficiency of this combined elbow and. tie-rod-bracket has been demonstrated in practice and it has been found that the combined structure stitfens the upper tank of. the radiator and atlords such a large anchor for the tie-rod that the strains will be distributed over a large portion of said tank and the tank will not be distorted. even under rough usage. Also. the combined structure described, is of small cost and insures the radiator bracket being; always properly positioned in respect to the upper tank con- {1 F nection or elbow and in respect to the upper tank.

l/Vhat I claim is:

1. An upper hose connection for the upper tanks of radiators having a tierodbracket formed rigid therewith.

2. The combination with an automobile radiator, of an upper hose connection in the form of a tubular elbow rigidly secured to the upper tank and provided with a tie-rodt o bracket formed integral therewith. and a tie-rod 2 directly secured to said bracket, whereby said hose connection aiiiords a large and extended anchorage for said bracke 3. An upper hose connection for the upper tanks of radiators, in the form of a tubular elbow having an outstanding flange eX- tending vertically and horizontally for engagement with the back and bottom of the upper tank, the vertical portion of said flange having a laterally offset upper end extension that afliords a tierod-bracket and is perforated for connection to the front end of a radiator tie-rod.

4c. In an automobile radiator hose connec tion, in combination with the tank and connecting conduit leading to the engine, of a bracket coupling member, formed of inte gral parts, consisting of an upwardly ex- 10 tending plate, capable of attachment to the tank Wall provided at its bottom with a downwardly extending ledge for engagement with the bottom of the tank, a rib on said upwardly extending plate and a clownwardly and outwardly extending hollow coupling member, said rib also being hol-V lowered out and merging with the hollow coupling member.
